  2. 16. A few aspects of aircraft noise

    Author : Crispin Dickson; Shafiquzzaman Khan; Mendel Kleiner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paired comparison; sorting based paired comparison; sorting algorithms; mergesort; quicksort; aircraft sound synthesis; aircraft noise; sound quality; tonal effects; angle positions; flight conditions; methods of equalization; cognition; Acoustics; Akustik;

    Abstract : A few aspects of aircraft noise were evaluated. These were (i) methods of subjective evaluations, (ii) effects of equalization and (iii) the effects of cognitive aspects.In the first paper, sorting algorithms were used instead of conventional paired comparison method in order to reduce the number of pairs in the evaluation of subjective judgments.

  4. 17. Studies of sound generation and propagation in flow ducts

    Author : Fabrice Ducret; Mats Åbom; Andy Moorhouse; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; two-port; plane wave; HVAC system; tailpipe; exhaust system; flexible duct; pipe; reflection coefficient; impedance; flow noise; vorticity; damping; scaling laws; impedance; transmission loss; perforated plate; slit; non linearity; Acoustics; Akustik;

    Abstract : This thesis contains three papers investigating problems of interest for noise control in ducts. The first part of this thesis treats the sound propagation in rectangular ducts with flexible walls. Various experimental techniques are performed to measure the internal sound propagation and radiation to the surrounding. READ MORE

  5. 18. In search for the conversational homunculus : serving to understand spoken human face-to-face interaction

    Author : Jens Edlund; Joakim Gustafson; David Traum; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Abstract : In the group of people with whom I have worked most closely, we recently attempted to dress our visionary goal in words: “to learn enough about human face-to-face interaction that we are able to create an artificial conversational partner that is humanlike”. The “conversational homunculus” figuring in the title of this book represents this “artificial conversational partner”. READ MORE

  6. 19. Alternative Measures of Phonation: Collision Threshold Pressure and Electroglottographic Spectral Tilt : Extra: Perception of Swedish Accents

    Author : Laura Enflo; David House; Jonas Beskow; Sten Ternström; Francisco Lacerda; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Abstract : The collision threshold pressure (CTP), i.e. the smallest amount of subglottal pressure needed for vocal fold collision, has been explored as a possible complement or alternative to the now commonly used phonation threshold pressure (PTP), i.e. READ MORE

  7. 20. Interactive computer-aided expressive music performance : Analysis, control, modification and synthesis

    Author : Marco Fabiani; Anders Friberg; Roberto Bresin; Petri Toiviainen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Abstract : This thesis describes the design and implementation process of two applications (PerMORFer and MoodifierLive) for the interactive manipulation of music performance. Such applications aim at closing the gap between the musicians, who play the music, and the listeners, who passively listen to it. READ MORE
